a6600 premium E-mount APS-C camera with 18-135mm Lens
Unparalleled AF performance, the key to beautiful shots
Fast and accurate autofocus captures fleeting moments in stunning detail, thanks to a combination of innovative Sony technologies. A total of 425 phase-detection AF points work in conjunction with contrast-detection AF to achieve a remarkable 0.02-s speed, while High-density AF Tracking Technology follows even erratically moving subjects.

Real-time Tracking holds the focus on tracked subjects
When you're tracking a fast-moving subject, the camera's motion tracker uses an enhanced subject recognition algorithm (AI) that draws on colour, pattern (brightness), distance (depth) and face/eye information to recognize, and maintain focus on, your subject.

Enhanced Real-time Eye AF supports portrait shooting
Real-time Eye AF detects and automatically focuses on the eyes of your subject when you half-press the shutter, and you can even prioritize your subject's left or right eye. When AF-C is set, it maintains a stable focus even when the face is partially hidden or backlit, or the subject is facing downward.
Real-time Eye AF for animal
The technology used in Real-time Eye AF has been adapted to support animal as well as human. When activated, this provides fast automatic detection and tracking of animals' eyes, with precise focus that had been difficult to achieve otherwise, all to give you great pet portraits and wildlife shots.
High speed continuous shooting with AF/AE tracking
Capture all the action with continuous shooting at up to 11 fps. Even when using silent shutter, or the live-view mode, up to 8 fps is possible. Display lag has been minimized, and up to 116 JPEG (Standard) images can be shot in each burst, with group display available in the playback mode.
Accurate autofocus in dim lighting
Highly accurate autofocus is possible even in dark settings, thanks to the camera's advanced AF algorithm. High AF sensitivity means reliable AF-S auto-focus all the way down to EV -2.
Focus Magnifier for finer focus adjustment in both MF/AF modes
When extra-accurate focus is called for, such as when you're taking macro shots, you can display a magnified view of the general area you want to focus on, then finely adjust the exact point of focus using the touchscreen or the focus point selector.
Easy manual focus with a clearly visible peaking function
The camera's peaking function colour-highlights the most sharply focused section of the entire image area when you're using manual focus. Now blue has been added to the display's other peaking colours (red, yellow and white) to improve the visibility of in-focus areas when you're doing the delicate focusing required for macro or portrait shooting.
Built-in 5-axis optical image stabilization
The 5-axis in-body optical image stabilization mechanism used on our acclaimed full-frame cameras has been adapted for use as a stabilization unit for the APS-C sensor on this model. This system compensates for camera shake along five different axes – pitch and yaw, horizontal and vertical, and rotational (roll) – to ensure steadier still images and movies during hand-held shooting. A highly accurate gyro sensor provides an image stabilization effect equivalent to a shutter speed 5 steps faster. The feature allows you to zoom in on far-off subjects, snap detailed close-ups, capture night scenes, and more ― all with minimal blur from camera shake.
An innovative image-processing system
The camera's APS-C size, 24.2-megapixel Exmor™ CMOS sensor provides a wide sensitivity range and excellent low-noise performance. In conjunction with the latest-generation BIONZ X™ image processing engine, it delivers beautiful, high-resolution images with superb image clarity and texture reproduction.
Extraordinary image quality, low noise and a wide ISO range
The standard ISO sensitivity range has been extended to ISO 100–32000 (expandable ISO 50–102400 for stills). Improved imaging algorithms, detail reproduction technology and area-division noise reduction result in more realistic textures, better detail in shadow regions, and more lifelike colours, including human skin tones and natural plant colours.
